T (all w/tont it may concern.-

Be it known that I, IVILLIE WRIGHT MITCH- ELL, Sr., a citizen of the United States, residing at Olive Branch, in the county of De Soto and State of Mississippi, have invented cer tain new and useful Improvements in Cultivators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cultivators for corn, cotton, and other similar crops; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

Figure 1 is a plan view of the cultivator. Fig. 2 is also a plan view of the cultivator, but shows the cultivator-shovels differently arranged. Fig. 3 is a longitudinal section taken on the line as a: in Fig. 1.

A is the center beam of the cultivator, provided with a draft attachment a at its front end.

B represents the two side beams of the cultivator. Each side beam has two longitudinal portions b and 0, arranged parallel with the center beam and at different distances from it.. An inclined portion d connects the portions 1) and c.

D is a portion bent at a right angle to the part b, which is nearest to the center beam, and d is a flange which projects longitudinally from the part D. D represents bolts which secure the said flanges (1 together and to the said center beam.

The rear end portions E of the side beams are twisted so as to form flat lugs, and e is a cross-bar which extends between the said lug and which engages with a notch e in the lower side of the center beam A. F is a loopbolt which passes over the said center beam and which secures the cross-bar toit. Grepresents uprights which project upwardly from the said lugs, and g represents bolts which secure together the said uprights, lugs, and the crossbar.

H represents the handles for guiding the cultivator. These handles are arranged in an inclined and diverging position. Their front ends are secured to the middle art of the center beam by a bolt h, and t eir middle portions are secured to the top portions of the uprights by bolts h.

Four curved standards I are provided, and each standard is provided with two bolts 6 at its upper part. The side beams haveTpairs of holes i in their parts 6 and "c for the bolts i to pass through, and the center beam A has pairs of holes and j. The holes are arranged in line with the holes i in the parts I), and the holes j are arranged in the rear end portion of the center beam A behind the cross-bar e. All the four standards are interchangeable and can be secured to the side beams or the center beam, as the fasteningbolts are arranged to engage with each pair of holes.

K represents cultivator-blades secured by removable bolts k to the lower end portions of the standards. These blades are also interchangeable, and a set of blades of different sizes and shapes is provided. A set of ten cultivator-blades or shovels is preferably provided for each cultivator.

When the standards and shovels are ar ranged as shown in Fig. 1, the cultivator is adapted for two rows. standards are removed and are secured to the center beam, the cultivator is adapted for three rows. The standard and shovel attached to the front part of the center beam can be omitted, if desired, or the said four standards can be secured to the said beams in any other preferred manner found desirable to suit different crops or the same crop in different stages of its growth.

What I claim is In a cultivator, the combination, with a straight center beam provided with a notch in the rear part of its lower edge, of two side beams having their front ends rigidly secured to the said center beam, each said side beam having straight portions arranged parallel with the said center beam and at different distances from it, and each said beam having bolt-holes arranged in pairs and at the same distance apart, a continuous cross-bar having its middle portion rigidly secured in the notch of the said center beam and its end portions rigidly secured to the said side beams, and interchangeable standards provided with cultivator-blades and airs of fasteningplolts for engaging with the said pairs of bolt- In testimony whereof vI have affixed my signature in the presence of two witnesses.
